Saw this sign this weekend on Sanibel Island. Did some research:
Timothy Noonan was a Boston Hairdresser from 1871 through 1880. His primary address was on Washington Street: at 723, then 913, and 910. From 1871 through 1873, he was listed as Hairdresser & Saloon. Some time after 1880, the company became known as "T. Noonan & Sons". In 1913, they registered "Petrole" as a Trade Mark. At that time, Frank M. Noonan was speaking for the company. In 1920, Frank M. Noonan, registered the Trade Mark "Zepp's," and claimed to have been using it since 1876. Fike also indicated that the Zepp's Dandruff Cure was advertised in 1930 and 1942. Note one variant has the word Petrole misspelled "Pretrole." The product "Petrole Dandruff Killer" was for sale in the 1901 Morrison & Plummer catalog.
Here a Noonan's delivery truck runs into some problems:
This ad from the Harvard Crimson (November 12, 1920):
Men with thin hair should not allow that little bald spot to grow larger and larger every month. One week's trial of Noonan's Hair Petrole will show what can be done with hair that is not entirely dead.
Noonan's Hair Petrole will soon rid the scalp of scales and dandruff, will give tone and renewed life to hair that is slowly dying from neglect. Rub a little in the scalp every night for seven nights and note how the hair appears to take on new life.
Barbers apply Noonan's Hair Petrole for fifteen cents, or obtain a bottle from drug and department stores, or direct from the manufacturers, T. Noonan & Sons, 33 Portland St., Boston, Mass.
And this from the Journal of the Indiana Stae Medical Association:
Noonan's Hair Petrole (T. Noonan & Sons Co.) contained 17.02 percent of alcohol, salicylic acid and about 12 percent of alcohol, salicylic acid and borax.
